Japan Alteplase Clinical Trial (J-ACT): Efficacy and Safety Study of Tissue Plasminogen Activator (Alteplase) for Ischemic Stroke

Summary

Based on previous studies comparing Duteplase\[a recombinant tissue plasminogen activator (rt-PA) very similar to alteplase\] doses, we performed a clinical trial with 0.6mg/kg, which is lower than the internationally approved dosage of 0.9mg/kg, aiming to assess the efficacy and safety of alteplase for the Japanese.
